IMPROVEMENT IN METALLIC RAKE-TEETH.

Specification forming part of Letters Patent No. 220,511, dated October14, 1879; application filed September 3, 1879.

To all whom it may concern:

Be it known that 1, WILLIAM M. WHITE, of Milford, in the county ofOakland and State of Michigan, have invented certain new and usefulImprovements on Metallic Rake- Teeth; and I do hereby declare that thefollowing description of my said invention, taken in connection with theaccompanying sheet of drawings, forms a full, clear, and exactspecification, which will enable others skilled in the art to which itappertains to make and use the same.

This invention has general reference to improvements on hand-rakes; andit consists in the peculiar construction and combination of parts, ashereinafter first fully set forth and described, and then pointed out inthe claim.

In the drawings already referred to, Figure 1 is a front elevation of arake-head provided with my improved teeth. Fig. 2 is a plan. Fig. 3 isan elevation of a separate tooth. Fig. 4 are modified forms of myrake-teeth.

This tooth I propose to construct of a sin gle piece of wire,(steel'wire being preferred,) as shown in Fig. 3, said wire being bentupon itself in the middle at a, and having near both extremities offsetsI).

The rakehead A, I provide with a proper number of apertures a, for thepassage of the shanks d of said wire teeth, and with grooves 6, whereinthe clinched ends f of said shanks c are embedded, so as to leave thetop surface of the rakehead smooth and even.

The teeth are inserted into the rake-head from its under side, so thatthe shoulders b on the teeth rest against the wood and prevent the teethfrom being drawn farther into the head than necessary, and the shanks dare made a suffieient length to protrude the head A, after which theyare bent or clinched into the grooves 0.

It will be observed that the teeth may be constructed to stand anydesired distance apart, the space between the teeth being arranged tosuit the various or any special requirements. If the teeth are to standvery close together, so that the shanks d (I would interfere with oneanother, I arrange the holes in the head in a staggering manner, as

shown in dotted lines in Fig. 1, which will thus allow the teeth to passeach other, and thereby accomplish the desired object in an expedientmanner.

The usefulness of this invention is apparent to every rake-user. Thespace between the wire teeth may be made so narrow that the finest hay cin be nicely gathered. The tooth is firmly set, and will stand far morepressure than the usual wooden teeth, and there is no breakingteeth,which is always annoying to the farmer and others.

It is self-evident that the teeth may be madelong or short, as occasionrequires, and that the parts a a may be spread farther apart or broughtclose together. So may a shoulder be formed on the wire by fasteningwashers or other projecting flanges on the parts a a, or by twistingeyes on them, as shown at X X, Fig. 4, without altering the nature of myinvention.

Heretofore wire rake-teeth have been made of one piece of wire bent toform a double tooth, and such teeth have been provided with shoulders,usually produced by turning or twisting eyes inthe wires, which eyeswere adapted to rest on or bear against the under side of the rake-head.I do, therefore, not claim such as my invention.

Having .thus fully described my invention, I claim as new and desire tosecure to me by Letters Patent Ahand-rake consisting of thehead A,pierced with a series of apertures, c, and provided with grooves c, saidhead being fitted with teeth formed of a single piece of wire, bent asspecified, and provided with shoulders I), the shanks d of said teethbeing passed through the head and clinched into the grooves 6,substantially as and for the object stated.

In testimony that I claim the foregoing as my invention I have heretoset my hand and afiixed my seal in the presence of two subscribingwitnesses.
